Hyperledger fabric 由于以前的块哈希不匹配，Hyperledger结构对等点死机

我有一个hyperledger结构网络，有2个组织，每个组织有2个对等点。我从备份中恢复了网络，对等方开始抛出以下错误：

我不确定哪里出了问题，但所有4个同龄人都开始抛出错误。关于下一步应该做什么有什么建议吗？

谢谢

您可能通过先备份对等方，然后备份订购方来备份网络

这是危险的，因为这样您创建的备份会导致对等方的块高度高于订购方

例如，假设订购方有一个最新备份的块100，而对等方有一个最新备份的块101，哈希值为

bar

。订购方将使用

foo

的散列创建块101，对等方将永远不需要拉取它。然后，订购方将使用先前的散列

foo

创建块102，但对等方期望先前的散列

bar
